Hi I get this message when I install LyX2 and try to use the sweave module:
Allows to use the statistical language S/R as a literate programming tool via Sweave package. See sweave.lyx in examples. Package(s) required: sweave->latex. Modules excluded: LilyPond Book. WARNING: Some required packages are unavailable! How do I find out which packages is missing? (I think "sweave->latex" is a converter not a package) Henry
